TYPE-WRITING-MAOHINE CLAMP.

Specification of Letters Patent.

Patented Dec. *7, 1909.

To all whom it may concern:

Be it known that I, EDWIN E. BARNEY, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- WVriting-Machine Clamps, of which the following is a specification.

My invention has for its principal object to provide an improved clamp for securing a typewriting machine or other machine to a baseboard or other support, such for example, as the shelf or platform of a drop cabinet.

In carrying out my invention, I have provided a simple and inexpensive device where by the typewriting machine may be clamped to or released from the baseboard or support by a single motion of the hand.

My invention consists in certain combinations and arrangements of parts, and features of construction which will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings illustrating my invention, Figure l is a front view showing a typewriter frame clamped to a desk or cabinet by means of my device, the typewriter frame being shown in transverse vertical section; Fig. 2 is a top view of a right-hand clamp in looking position; Fig. 3 is a side view of the same; and Fig. 4 is a vertical section on the line m-m of Fig. 2, looking in the direction of the arrow.

In the drawings, 1 designates the base to which the typewriter is secured. As shown in the drawings, this consists of the platform of a drop cabinet, said platform being supported in part by pins 2 which project from the side edges thereof into slots in the faces of the side pieces 3 of the cabinet. This cabinet may be of any suitable construction. As ordinarily constructed, the platform 1 is depressed below the general level of the top of the desk and is so an ranged that it may be lowered in a slanting I of said ears.

position and a lid drawn over it, thus cona base portion which comprises a left-hand side plate 4 and a right-hand side plate 5 extending in a front and back direction and the frame is supported on feet 6, which are usually made of rubber and which elevate the side plates 1 and 5 above the support on which the machine rests. I secure headed pins 7 to the side plates 41 and 5, preferably on the inner sides thereof; and my clamps comprise coupling members 8 which engage these pins or projections and hold the machine in place. Each of the clamps employed has a flat base portion 9 which is secured by screws 10 to the support 1. From the right and left-hand sides of the base 9 rise ears 11 in which is journaled a shaft 12 which passes loosely through suitable openings in the two ears 11. On one end of the shaft 12 outside of the ear 11 is rigidly secured a crank arm 13 having a handle 14: on its free end. Into the other end of the shaft 12 a headed screw 15 is threaded eccentrically, the axis of the screw being parallel with the axis of the shaft. A sleeve 16 (Fig. 4;) surrounds the screw 15 and is clamped between the end of the shaft and the head of the screw. The coupling member 8, as shown in the present instance, consists of a suitably formed hook or latch having at its lower end an opening by which it is journaled on the sleeve 16. A friction washer 17 is compressed between the hook 8 and the end of the shaft 12. The washer 17 is preferably made of leather or similar material. The construction is such that when the shaft 12 is turned by the handle 14:, the hook 8 tends to turn therewith on account of its frictional connection with the shaft 12 and screw 15; but the shaft may be turned independently of the hook if the latter is held by any means. Endwise motion of the shaft 12 in one direction is prevented by the crank arm 13 engaging one of the ears l1 and such motion in the other direction is prevented by the washer 17 engaging the other This frictional engagement of the washer 17 with the ear 11 tends to hold verting the typewriter cabinet into a desk i the shaft 12 against accidentalrotation. The

having a flat top, the typewriter being inclosed between the lid and the base or platform 1. When the desk is thus closed with the base 1 dropped, said base is inclined downward, and it is therefore necessary that the typewriter be firmly clamped in place.

The frame of the typewriting machine has motion of the hook or catch 8 toward the back of the machine is limited by a pin 18 which projects from one of the ears 11 into the path of said hook. The shaft 12 is free to turn through about a half rotation, its motion being limited by the engagement of the arm 13 with the baseboard. The arm 13 and the eccentric screw 15 are so arranged with relation to each other that when said armstands in a horizontal position toward the front of the machine, the eccentric stands approximately vertically beneath the axis of the shaft, being either on the dead center or a little past it; but if the arm 13 be turned to a horizontal position toward the back of the machine, the eccentric stands approximately vertically over the axis of the shaft.

The clamp is screwed to the baseboard in such position that when the typewriting machine is placed on said-baseboard the side plate 41: or 5 stands above the shaft 12 as shown in Fig. 1, the hook 8 being inside of the framework of the machine in position to engage the pin or stud 7 and the crank arm 13 and handle 1 1 being outside of the frame work in position to be readily grasped by the hand of the operator. I may use either two clamps, each being placed midway of one of the side plates, or four clamps, two to each side plate, as may be preferred.

When the machine is set on the baseboard the handles 141 extend toward the back of the machine and the hooks 8 are in engagement with their stop pins 18, said hooks then standing in an inclined position behind the. pins 7. The handles 14 are then turned toward the front of the machine. The hooks 8 turn with the shafts 12 toward the front of the machine until they are arrested by the pins 7, after which the movement of the handles 1 1 is continued and the eccentric screws 15 are turned to their lowest position, shown in Fig. 3, thus drawing the hooks down tightly against the pins 7 and clamping the machine firmly and under tension in place. When it is desired to remove the machine from the baseboard, the handles are turned to their rear positions, the turning of the shafts 12 moving the eccentric screws to their highest positions and thus relieving the pressure or tension between the hooks 8 and pins 7. As soon as this pressure is sufficiently relieved the hooks 8 are moved back by their frictional connection with the shafts until said hooks are arrested by the pins 18. In this position of the parts the machine is entirely free from the clamps and may be lifted off the baseboard and the clamps themselves are in position to reengage the pins 7 Whenever the machine is replaced.

It will be perceived that the machine is clamped in place by a single movement of the hands of the operator and is released by a single movement. It will also be perceived that all of the parts of the clamp are on top of the baseboard where they are readily ac oessible and that the handle is outside of the machine frame and the hooks on the inside thereof.

Various changes may be made in the details of construction and arrangement without departing from my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a baseboard clamp for machines, a horizontal rock shaft mounted on said baseboard and extending beneath a lower frame piece of the machine, a handle on the outer end of said shaft, a hook pivotally mounted on the inner end of said shaft to swing in a vertical plane, a stud on the machine in position to be engaged by said hook, and a washer of pliable material tightly held between the outer face of said hook and the inner face of said shaft with sullicient tension so that when the shaft is turned the hook may be swung therewith to a position in which it engages against the stud.
